A student throws a long stick of length 0.11m and mass 0.5 kg into the air in such a way that the center of mass rises vertically. At the moment it leaves his hand, the stick is horizontal and the speed of the end of the stick nearest to him is zero. When the center of mass of the stick reaches its highest point, the stick is horizontal, and it has made 15 complete revolutions. How long did it take for the center of mass to reach its highest point? Assume the stick's cross sectional area and mass is uniform. The acceleration of gravity is 9.8 m/s^2. Answer in units of s.

Despite their crazy structure, human bones are surprisingly good!

Answer;

hot magma rises and pushes up toward the lithosphere, and as it cools it cycles back down toward the core to be heated again.

explanation; convection currents are the circular pathways taken by a fluid that enhances heat transfer by the process known as convection which occurs in fluids.convection currents transfer heat from one place to another by mass motion of a fluid. earth mantle is in a semi-liquid state and behaves like any other fluid, rising up from the bottom of the mantle after becoming hotter and less dense from heat of the earth's core, as the rock loses heat into the earth's crust it becomes cooler and more dense, then sinking back down to the core, then repeating the cycle.

Well in that case, since an object moves with a constant velocity, there will be no acceleration as it is not increasing in speed.
